The Jaguar XFR-S is the most powerful member of the XF and is on sale from July 2013 by 126 202 euros. It is 16 988 euros more expensive than the version XFR .Compared with its main alternative, is priced higher than a BMW M5 or Mercedes-Benz E 63 AMG . An Audi RS 6 Avant is more expensive, but only sold with all-wheel drive station wagon.
Has a petrol engine with eight cylinders in 'vee', five liters of displacement,turbocharging and direct injection . Da 549 maximum horsepower, or 39 more than the XFR, with which it shares the engine. The traction on the rear wheels.
The power increase is obtained by varying the engine management, improving the air into the cylinders and optimizing the output of the combustion gases through the exhausts. The gearbox is the same as that used by the F-Type -called 'Quickshift' - has eight speeds and can be controlled manually with paddles behind the steering wheel.
It can accelerate from 0-100 km / h in 4.6 seconds -3/10 second unless the XFR-and its top speed is electronically limited to 300 km / h, in the XFR is 250 km/h-. According Jaguar average fuel consumption has not changed with respect to the XFR, so this is 11.6 l/100 km. The automatic engine stop-start is standard in detention.
The data mentioned in the previous paragraph are worse than those of some of its main alternatives. For example, a BMW M5 has 560 hp, accelerates from 0-100 km / h in 4.3 seconds and consumes an average of 9.9 l/100 km, while a Mercedes-Benz E 63 AMG with 557 hp, accelerates from 0-100 km / h in 4.2 seconds and consumes an average of 9.8 l/100 km.

Also modified the operation of various electronic systems driving aids such as the electronic suspension management adpatativa, the stability control and the differential -mail.
Moreover, the body has various aerodynamic modifications, including highlighting the two different types of rear spoiler available.Jaguar generally stated that these modifications reduce aerodynamic lift by 68%. All this contributes, as Jaguar, to improve cornering, increased stability and limiting linear side body movements.
It has 20-inch wheels-called 'Varuna' - on which are mounted tires measuring 265/35 at the front axle and 295/30 at the rear -255 / 35 and 285/30 in the XFR respectively. The brake system consists of four ventilated discs with a size of 380 mm front and 376 mm rear.
